案例代码

type RestFulHello struct {}

func (r *RestFulHello) SayHello(b *restful.Context) {

	b.Write([]byte("get user id: " + b.ReadPathParameter("userid")))
}
func (r *RestFulHello) SayHello1(b *restful.Context) {

	b.Write([]byte("get user id1: " + b.ReadPathParameter("userid")))
}
func (r *RestFulHello) URLPatterns() []restful.Route {
	return []restful.Route{
		{Method: http.MethodGet, Path: "/sayhello/{userid}", ResourceFunc: r.SayHello},
		{Method: http.MethodGet, Path: "/sayhello1/{userid}", ResourceFunc: r.SayHello1},
	}
}
func main() {
	// register struct
	chassis.RegisterSchema("rest", &RestFulHello{})
	//start all server you register in server/schemas.
	if err := chassis.Init(); err != nil {
		openlog.Error("Init failed. "+err.Error())
		return
	}
	chassis.Run()
}
